To all whom z'tmay concern.'

Be it known that. we, ALFRED A. GLIDDEN and Josemi E. PERRAULT, citizens oi' the United States, and residents of Watertown, in the county of Middlesex, in the State of lvlassachusetts, have invented certain new and' useful `improvements in Battery Boxes, of which the following is a specification.

Uur present invention relates to improvements in hard rubber battery boxes or jars of the type which are formed with a plurality of partitions toi-ming cells for the active material, and more particularly to the improvements in the handle construction. These battery jars are now very extensively used in connection with starting, lighting and ignition systems ot' motor vehicles. Owing to the vibration and jolting to which the Inotor vehicles are subjected in service, it is necessary that the' storage batteries should be firmly secured in place in the machine, and owing. to the weight of the batteries, handles must beprovided 'l'or lifting them when necessary, and it is the custom to apply the clamping means lor holding the battery in the machine to these handles.

lt has been customary in connection with hard rubber battery boxes to use metal handles at opposite ends ot' the box secured by screws passing through the attaching plates and engaging nuts embedded in the rubber ot' the box, by means of which screws the handle plates have been secured directly to und against the end faces ot the boxes. In the shaking and jolting of the motor Vehicles when in use, it has been found that the acid comes up through the vent plugs and overllows to the end of the box where it comes in Contact with the handle and causes a corroding action, and following the handle down to the screws corrodes them, the corrosion eventually extending into the nut and around the head of the screw to the handle. This makes is ditlicult to remove the screws tor repair or replacement of the handles, and also shortcns the lite of the handles.

The object ot the presentinvention is to provide a handle construction or means ot' attachment which will be tree from these objections and the invention includes the 'novel features ot' construction and arrangement. and combination oi' parts hereinafter drawings, the numeral l desi nates a hard rubber battery jar of the usua construction having embedded in the en walls thereof anchoring means such as nuts 2 which are designed to cooperate with the attaching screws 3 which pass through the handle members 4. In order to avoid the corroding eli'ect ol the acid, the handle members are spaced `'roni the end walls oi' the battery jar or box by interposed acid-proof spacing means so that any seepage of acid may take place down the outside tace of the battery boxy without contact with either the metal handle or the attaching screws, whereby corrosive action is prevented.

One means of accomplishing this is to provide around. the screws and between the tace of the box and the inner 'tace of the handle, rubber washers as indicated at 5. These washers serve to space the handle members'and to protect the screws from any acid seepage.

Instead of using rubber washers as hereinbctore described, we may, in the molding of the box, form the end walls with integral hard rubber bosses, as indicated at 5, against which the handles are clamped and which serve to space them from the box walls. TWhere hard rubber bosses are used, we pref'- erably coat the outer faces ot' the bosses willi a rubber cement so that when the screws are tightened up, a hernietically sealed joint is provided between the inner face ol the handle and the outer faces of the bosses.

'lhe handles as before desifribcd, in addi1 tion to serving the fuiuftion oi' handles for lifting the box, are adapted to be engaged lowing manner.

bythe held-'down clamps for holding the battery in -place in the motor vehicle. o

.These holddown clamps exert a great deal of strain, and to provide a handle which will be strong and yet light', and to distribnte the strain so as to prevent any liability et breakage of the end walls of the box, we construct the handle and attach it in the foloi' sheet metal, having a body portion of substantially triangular shape with the apex oit' the triangle pointing downwardly and this body portion is made of a width corresponding to the width of the end walls of the box. The nuts for engagement with the screws through the ends or wings of the handle.. are thus embedded in the body of the box near the upper edge in line with the side walls oi the box,Y as shown so that any force or pressure applied to th tions fla oi' the handle is sustained by the s Avde walls, and thus the intermediate portions of the end walls are relieved of such outward Strain. By extending the central apex portion of the handle body downward to a material distance, the leverage is such that very little pressure is imparted to the end wall by anyy tendency of the handle to rock on its upper secured screws under the outwardpressure referred to. The handle is constructed by stamping upI from sheet metal into the proper shape, a portion of the metal being removed to provide upwardly extending members 4b which are connectedat their upper ends by the integral handle portion et above referred to.

To stillen the handle members and enable them to be constructed of lighter sheet metal than would otherwise be possible, we provide'tlieni with integral cross ribs 4c formed A thev handle is constructedA e gripy pornoname by stamping or dieing up the metal, which cross ribs are in line with the end attachinfr screws, and we also provide vertical strengthening ribs 4d extending upwardly into the hand grip member carrying portions. The portion of the sheet metal which forms the grip portions is stamped in a curved form, as shown, and small centrally disposed recesses a are provided for securing the attaching clamps.

Instead of embedding nuts in the Walls and providing screws to engage therewith, it is obvious that this construction could be reversed as shown in Fi g. in which event the anchoring means may be in the form of pin 3 having a flared oi' pronged head 3l embedded in the box Wall, the outer endof the pin passing through the handle opening and being threaded to receive the clamping nut 2".

Having thus described the said invent-ion, what is laimed as new,`is:-

Thecoinbination with a container formed entirely `of acid-prootl material, of a pair of rigid sheet metal handles carried thereby, said handles having handle portions adapted to receive the thrust of hold-down devices7 and having substantially triangular portions overlying the end Walls of the container, Vmetallic securing devices for securing the said triangularl portions to the box walls 'at slightly spaced points, .said tri angular portions being held spaced from the `end walls ot' the container by acid-proof.

spacing means surrounding said securing means.

In testimony whereof, We ailix our signatures. 4
